  • Device and method for transmitting data in a wideband wireless network and computer program product
    Patent number: 8369844
    Abstract: A device for transmitting data in a wideband wireless network. The device may include a transmitter for transmitting data via a channel of the wideband wireless network, the transmitter is arranged to start the transmitting in response to a start signal. A first transmission controller is connected to the transmitter, for controlling transmission of data by the transmitter. The transmission controller includes an energy detector for detecting the amount of energy in the channel. The energy detector is arranged to repeat the detecting in response to a repeat signal. A comparator is connected to an output of the energy detector and to a control input of the transmitter. The comparator is arranged to compare the detected amount of energy with an energy threshold, to output the repeat signal to the energy detector in case the detected amount of energy exceeds the energy threshold; and to output the start signal to the transmitter when the detected amount of energy is below the energy threshold.
